l To all whom it may concern:

.made in stock and are applicable each to any Be it known that I, LEONARD A. YOUNG, a citizen of the United States, residing at Detroit, in the county of-Vvayne and State of .Michigan, have invented certain new and useful Improvements in Upholstery- Sprmg Constructions, of which the following is a specification,

In the appliance of cushion backs to vehicles or the like, it is desirable that the structure be so arranged that the upholstery trimmer can quickly and easily place the same in the vehicle body or furniture frame after the structure itself has been assembled and completed so as to form a unit.

It is further desirable that the component parts of the structure be arranged so that the body springs with theirconnecting and supportin parts-may be assembled in a' unit separate gem the base which must conform to the particular shapes of the seat back frame or tonneau for which it is designed. That is, the supporting base of the spring back of a vehicle tonneau for example, must conform to the particular design of that particular vehicle while the body spring unit need not, and can be made up in quantities for application to any one of a number of bases that are themselves usable only each for its particular place.

This invention relates to back spring structures and to an arrangement thereof whereby a base is provided that is appl ed readilyand quickly to the particular support for which it is intended while the body springs form unitary structures that' are one of a number of bases that are individual in dimensions and form, the base and body spring structure with the applied upholstery when united being adapted to be detachably mounted in a tonneau or the like.

The invention consists in the matters hereinafter set forth and more particularly pointed out in the appended claims.

In the drawings Figure 1 is a wow in front elevation, par-- tially broken away to give clear view, of a base and back spring unit'assembled in structure that embodies features of the invention;

Fig. 2 is a View in transverse section therethrough;

Fig. 3 is a view in perspective of the base and-of the rim and frame of the body, the springs of the structure being omitted; and

. Fig. t is a view in detail of a preferred .means for securing certain of the parts toand a longitudinal outer channel the first for the reception of the end portions of transverse members 2 of the case and the latter for the retention of the marginal portion of'an applied upholstery cover.

Retention of the end portions of the bars 2 is obtained by squeezing the upper flange 5 of the strip 1 upon the inserted bent end partsof the bars. A bottom strip 6 is preferably of the same S-section as the strip 1, at least in so far as it provides an inner groove for the reception and the retention of the lower end portions 7 of the members 2 by bending over and clamping down the flange 8, and an outer groove indicated at 9v for the upholstery cover margin, completes the base. The upper member 1 is bent or curved to conform to the supporting rail is provided with a longitudinal inner groove or partof the tonneau to which it is applied while the lower strip 6 is likewise designed to seat uponthe frame of the tonneau and be retained there as by a ledge member of suitable angle section indicated at 10. Where the end portions or arms of the strip 1 are curved as shown at 11, a brace bar 12 spans the interval between them and acts as a support to the upper edge portion of ap lied upholstery.

at may betermed a back spring unit is applied to this base which latter, as clearly indicated, may be made to conform to any means as for example by U strips 16 in' which the base turns of the marginal springs 1 are secured. Other stay members 17 and clips 18 prevent local side motion of the springs. v

An rim. frame 19 connects the top turns of the body springs to which'it is se cured as by clips 20. If the rim frame extends beyond the body springs, so that the end rail 21 thereof lies at considerable distance from them, an intermediate bar 22 may be applied, the latter being secured by clips 23 to the springs and have an ofl-set portion Qa'that is connected as by a chp 25 to the end rail 21.

The back spring unit rests upon the members 2 of'the base holding members unit ing the parts. In preferred construction, the holding member 35 is a clip having a central loop with outturned angle arms 26 that lie in the channel. of the strip 13 and are firmly locked by. compression of the flanges as at 27 between the sides of the loop and out-turned -end portions 28- of such arms. As a further means. of preventing motion between the base and the body unit, anchor strips 29 connect the frame 13 with the lower base rail 6, the end portions of the j angle strips being clenched between the flanges of the members to which they are secured. As a further means to stay the structure, transverse braces 30 connect the bar 12 with the farther side' of the frame 13. The usual filling 31 and cover fabric 32 is placed on the assembled structure and the marginal portions of the cover are held in the grooves of the S-strips 1 and 6.

Suitable provision is made for securing the assembled structure to the supporting of bases,

frame of the tonneau. This may take the f' form of depending lips 3 struck from the 3.5 v 4 or behind suitably designed socket plates 4 body of the strip 1 and adapted to slip into that may be. screwed, nailed or otherwise fastened to the upper part of the tonneau, While the retaining flanged bar 10 or the like acts as a retaining ledge behind which the lower margin'of the structure is placed.

One feature of the construction is theadaptability of the same to quantity production where the back is being applied to tonneaus, base frames are made up each conforming to a particular tonneau. The body spring units are standardized, within limits, to the general dimensions of the base and can be used interchangeably with any of these bases. As a consequence, back springs may 'be made up in stock quantity and be used with several different sizes or forms each form for a particular type of tonneau. The assembled structures, fully trimmed, are readily slipped into position in the tonneaus and as readily removed for cleansing and the like. When the body units are placed each upon a base, upholstery is quic (ly applied to the assembled structure in the shop and the latter is readily and easily shipped to any place desired. and anchored in position in thetonneau without further trouble on the part of the person fittincr out the vehicle.

6bviously, changes of the details inconstruction may be had without departing from the spirit of my invention and I do not care to limit myself to -any particular form or arrangement of parts.

What I claim is 1. A seat back comprising a main frame conformed to a supporting back and pro vided with means along its margins for retaining upholstery covering, and a back spring unit structure mounted on the main frame and provided with upholstery, the cover of which is secured to the retaining means of the main frame.

I I
